유방의 낭성샘근육상피종 -1예 보고-

Abstract

Adenomyoepithelioma of the female breast is a rare tumor. With rare exceptions, the tumor is uniformly solid. We describe a large grossly cystic adenomyoepithelioma in a 67-year-old female. The tumor was histologically benign. The characteristic microscopic finding was the proliferation of rounded tubules lined by both epithelial and myoepithelial cells. Immunohistochemical findings confirmed the presence of two cell population.
